Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection devices, in particular to a vertical radial runout detection device for a slewing bearing. Background Art

[0002] A slewing bearing is a large bearing that can bear comprehensive loads. Slewing bearings are often installed in horizontal working conditions. When manufacturing enterprises assemble and detect the radial runout of slewing bearings, they are all detected on horizontal detection devices. The axial clearance and radial clearance of the slewing bearing have little mutual influence on the radial runout error of the inner and outer rings. When the slewing bearing is applied in a vertical working condition, due to the relatively large radial and axial clearances of the slewing bearing, and at the same time, the separation spacer blocks and rotational runout errors adopted by the slewing bearing are superimposed together, there is a large error between the detected value and the value detected horizontally.

[0003] In order to make the rotational runout value of the slewing bearing meet the use requirements of the vertical working condition and ensure stable transmission when applied in the vertical working condition, it is necessary to detect the radial runout value of the slewing bearing under vertical conditions. In view of this, the applicant has designed a vertical radial runout detection device for a slewing bearing Summary of the Utility Model

[0019] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0020] As Figures 1 - 3 A rotary bearing vertical radial runout detection device as shown includes a base 16. A bent support member 12 is installed on the top of the base 16. The top end of the bent support member 12 is connected to a first runout detection instrument 3. The detection probe of the first runout detection instrument 3 is in contact with the outer wall of the outer ring 1 of the slewing bearing. Two screw holes and two pin shaft insertion holes are respectively formed on the side surface of the bent support member 12. A positioning bolt 6 is threadedly inserted into the two screw holes, and a positioning pin shaft 7 is inserted into the two pin shaft insertion holes in a matching manner; it further includes a cone block 19. The cone block 19 is installed with a first connecting block 17 through a connecting mechanism. A second runout detection instrument 4 is arranged on one side of the first connecting block 17 and is in contact with it (the detection probe of the second runout detection instrument 4 is in contact with one side of the first connecting block 17).

[0021] In this embodiment, when detecting and measuring the radial runout of the inner ring 2, the outer ring 1 is fixed on the bent support member 12 through the positioning bolt 6, and then the inner ring 2 is rotated to rotate in the outer ring 1. The inner arc surface of the inner ring 2 slides relative to the cone block 19, and the cone block 19 transmits the force to the detection probe of the second runout detection instrument 4. During this process, the second runout detection instrument 4 detects the average value of the radial runout of the inner ring 2. When detecting and measuring the radial runout of the outer ring 1, the inner ring 2 is fixed on the bent support member with the positioning pin shaft 7, and the outer ring 1 is rotated to rotate on the outer surface of the inner ring 2, and the average value of the radial runout of the outer ring 1 is read on the first runout detection instrument 3.

[0022] One end of the cone block 19 is connected to a connecting plate 20. One end of the connecting plate 20 is installed with a rotating shaft 14. One end of the first connecting block 17 is installed on the side surface of the rotating shaft 14. The bottom end of the rotating shaft 14 is rotatably sleeved with a fixed circular ring member 21. The bottom end of the fixed circular ring member 21 is installed on the surface of the bent support member 12. A support rod 15 is installed on the surface of the bent support member 12. The top end of the support rod 15 is installed at the top end of the rotating shaft 14 through a bearing.

[0023] In this embodiment, as the inner ring 2 rotates within the outer ring 1, the tapered block 19 slides along the inner circular surface of the inner ring 2. The tapered block 19 produces slight jitter on the inner circular surface of the inner ring 2. After the tapered block 19 is stressed, it drives the rotating shaft 14 to slightly rotate between the fixed ring member 21 and the support rod 15, drives the first connecting block 17 to slightly rotate and apply force to the detection probe of the second jitter detection instrument 4, facilitating the second jitter detection instrument 4 to detect the radial jitter value of the inner circular surface of the inner ring 2.

[0024] A fixed block 13 is installed on the side of the support rod 15. The second jitter detection instrument 4 is installed through the side of the fixed block 13. The fixed block 13 can fix the position of the second jitter detection instrument 4, improving the stability of the second jitter detection instrument 4 for detecting the radial jitter of the inner ring 2.

[0025] A second connecting block 18 is connected to the surface of the first jitter detection instrument 3. One end of the second connecting block 18 is installed on the surface of the bent support member 12. The second connecting block 18 is used to fix the first jitter detection instrument 3 on the bent support member 12, improving the stability of the first jitter detection instrument 3 for detecting the radial jitter of the outer ring 1.

[0026] A camshaft 10 is provided below the outer ring 1. Both ends of the camshaft 10 are rotatably sleeved with support plates 11. One end of the two support plates 11 is installed on the surface of the bent support member 12. One end of the camshaft 10 is connected with a handle 9. By rotating the handle 9, after the handle 9 is stressed, it drives the camshaft 10 to rotate on the two support plates 11. During the rotation process, the cam part in the camshaft 10 pushes the outer ring 1. After the outer ring 1 is stressed, it drives the slewing bearing to move slightly up and down, so that the detection probes of the first jitter detection instrument 3 and the second jitter detection instrument 4 can respectively maintain appropriate contact with the outer wall of the outer ring 1 and the inner wall of the inner ring 2 during the detection process.
